Bob,Just looking at the eBay listing - aren't they awfully bright? Just thinking compared to using the 5050 led strips for edge lite signs. I have never made a litho, so I am asking for reference as much as anything. It certainly reduces parts required any prep work. Thanks,Scott

They are bright. But they can run on 9VDC.I like a bright light behind my litho's. With these I can tweek my picture so its a little thicker in the light area's.I guess simplicity is the thing I like about them, and of coursethe price.olf20 / Bob
